The caliper spraypainting can only add a layer of paint on the original caliper, and thepaint will become black under the influence of brake dust for a longtime. In addition, paint spraying itself is also very troublesome.

At present, caliper covers on the market are divided into universalcalipers and dedicated caliper covers, and the universal caliper coverneeds to be glued. If brake pads need to be replaced, detaching thecaliper cover will be very difficult, and it is not safe during use. Atthe same time, it will also affect the heat dissipation of the caliper,and the shape does not match because the original caliper isever-changing and cannot completely wrap the caliper; and the dedicatedcar caliper is obtained by punching through an arc-shaped plane die withan aluminum alloy plate, has an arc-shaped plane profile, can cover theoriginal caliper, and is fixed and installed with a buckle. In addition,the existing caliper cover has obvious defects due to the design of afixed structure: the buckle is too large and too long, a connectionbracket is too long, the amount of buckle deformation is large, theamount of bracket deformation is large, and the clamping force of thebuckle is insufficient, which easily causes the caliper cover to shakeand rub against the wheel hub.

The elastic pressing sheet 132 is hingedto the first arc-shaped side plate 140, and a spring clip 131 isprovided between the elastic pressing sheet 132 and the first arc-shapedside plate 140. Specifically, the elastic pressing sheet 132 is combinedwith a heat transmission silicone sheet, and the temperature of a pistonpump body of the caliper is higher during brake and also requires heatdissipation. In an embodiment of the present invention, through thecombination of the elastic pressing sheet 132 and the heat transmissionsilicone sheet, the caliper cover body 100 is connected to the pistonpump body of the caliper, and the high temperature generated by thepiston pump body can be quickly transmitted to the caliper cover body100 through the heat transmission assembly, such that the heat iseffectively dissipated, thereby reducing the temperature of the brakecaliper. In the heat transmission assembly 130, the heat transmissionsilicone sheet is combined with the elastic pressing sheet 132, and heattransmission silicone can fill a gap and fully contact with a heatingpart of the piston pump body. The spring clip 131 is used to ensurepressure required for the connection between the elastic pressing sheet132 and the car caliper pump body, and when the piston pump body of thecar caliper moves slightly due to wear of the brake pads, good pressureand connection performance of the elastic pressing sheet 132 can bemaintained, thereby ensuring the continuity and effectiveness of heatdissipation of the car caliper. At the same time, since the cover body100, the fixing member and the elastic pressing sheet 132 are all madeof an aluminum alloy material, the entire car caliper cover has a goodheat dissipation performance.

Wherein the fixing member comprises a first fixing member 110 and asecond fixing member 120, which are respectively mounted on two sides ofthe first arc-shaped side plate 140; and the first fixing member 110comprises a connection bracket 114 a, a first bent portion 111 fixedlyconnected to the connection bracket 114 a, and a second bent portion 112cooperating with the first bent portion 111 and fixing the connectionbracket 114 a to the car caliper. The second fixing member 120 comprisesa connection bracket 114 b and a fixing buckle 121 fixedly connected tothe connection bracket 114 b, the fixing buckle 121 being used forfixing the connection bracket 114 b to the car caliper. The first bentportion 111 and the second bent portion 112 are fixedly connected by abolt. Specifically, the connection bracket 114 is a 2 mm 6061T6high-strength aluminum alloy plate. The connection bracket 114 has atleast one bent portion. Preferably, the connection bracket 114 has twobent portions to enhance the strength of the connection bracket 114 andfacilitate joint installation of the connection bracket 114, and at thesame time the heat conducted to the cover body 100 can be dissipated.The first bent portion 111 and the second bent portion 112 are both madeof a high-strength stainless steel spring sheet, and the hardness of thespring sheet reaches 400. By the design of the first bent portion 111and the second bent portion 112, the fastening strength of the fixingmember is greatly improved, and the car caliper cover can be firmlymounted on the car caliper.

In an embodiment of the present application, the first fixing member 110and the second fixing member 120 are provided on the two sides of thefirst arc-shaped side plate 140, and fixing devices of the two fixingmembers are different. Wherein the first bent portion 111 is fixed to athree-dimensional folded edge provided on the connection bracket 114 aby two stainless steel semi-hollow rivets, and the three-dimensionalfolded edge is provided with a hole for a screw to pass through to fix ahexagon socket head cap screw 113. The second bent portion 112 has athree-dimensional folded edge, which increases the strength of thesecond bent portion 112, the three-dimensional folded edge is providedwith a hole for a screw to pass through to cooperate with the hole ofthe first bent portion 111, and the hexagon socket head cap screw 113 isused for connection and fixation. The device is simple in structure,firm in fixation, and fast in installation, the caliper cover can befirmly fixed to the caliper only by the hexagon socket head cap screw113 and a nut, and the problem of deformation and shaking of the calipercover is minimized. The fixing buckle 121 of the second fixing member120 is fixed to the connection bracket 114 b via two stainless steelsemi-hollow rivets, and the connection bracket catches a gap betweenbrake discs of a caliper bracket by the folded edge. The caliper coveris fixed by the first fixing member 110 and the second fixing member120, and is then fastened by the stainless steel screw 113 and alocknut, thus the caliper cover is more safe and reliable, and assemblyand disassembly thereof are convenient and cost less time. Since thecover body 100 is entirely made of an aluminum alloy material, and isfixedly connected to the caliper through an aluminum alloy customconnection bracket 114 above the caliper cover, the heat of the calipercan be dissipated through the aluminum alloy caliper cover with a goodheat dissipation function.

The surface of the cover body 100 of the embodiment of the presentapplication is coated with a layer of electrostatic powder coating,which has excellent UV and salt mist resistance and corrosionresistance, especially for brake dust, and is particularly convenient incleaning without discoloration.

As shown in FIG. 3, an expansion insert 150 is fixedly connected to thecover body 100 near the second arc-shaped side plate 160. The expansioninsert 150 can be designed according to the shape and size of thecaliper. By replacing different expansion inserts 150, car calipers ofdifferent specifications can be met.
